Inventor: MARKUSSEN JAN
IPC: C12P21/00
Filed: 1987-07-20
Granted: 1991-07-11
Abstract: Insulin derivatives of the general formula I <CHEM> and having a charge which is positive compared with the charge of human insulin at neutral pH, can be used to prepare solutions having prolonged insulin action. In the novel insulin derivatives, a basic amino acid has been substituted in the B27-position and/or a neutral amino acid has been inserted in the A4-, A17-, B13- and/or B21-position. The C-terminal of the A-chain, Asn<A21>, may be substituted by another amino acid in order to increase the stability of the solutions at the slightly acidic pH of pharmaceutical solutions. Furthermore, the C-teminal carboxyl group of the B-chain may be blocked with an amido or ester residue. Provided that A21 is Asn, the carboxylic acid group of B30 is free.

Title: Process for doping aqueous solutions with acrolein in biocidally active concentrations
IPC: C02F1/50
Filed: 1991-12-02
Granted: 1993-08-19

Title: High speed camera shutter - has liq. crystal filter plate and electronic control ensuring low inertia
IPC: G03B7/08
Filed: 1971-11-17
Abstract: A high speed, low inertial camera shutter has a liq. crystal filter (11) linked to the exposure control and to a mechanical shutter drive. The filter is switched into a transparent state for the required exposure time and provides a rapid shutter action, with no moving edges. For exposure the liq. crystal is energised to block the light and the mechanical shutter is moved aside.

Patent JP-H0142002-B2 (JP)
IPC: H02H3/24
Filed: 1982-03-30
Abstract: In a circuit arrangement to be coupled to an electronic element (38), such as a microprocessor, and a power source circuit (21, 23, 24) providing a source voltage V which builds up at a transition to energize the electronic element and which is subjected to a momentary interruption and restoration therefrom, a detection circuit (55, 56) is coupled to the power source circuit to distinguish between the transition and the restoration by monitoring the source voltage to produce an enable signal only upon detection of the transition. Such distinction is possible by the use of a combination of a time constant section (55) with a switch (56). Responsive to the enable signal, a pattern generator (51) produces a pattern signal stored therein. A predetermined initial operation is carried out by the microprocessor in response to the pattern signal upon occurrence of the transition and is not carried out upon occurrence of the restoration. Thus, the electronic element is capable of continuing a previous operation prior to the momentary interruption.

IPC: B01D53/14

Granted: 1996-06-12
Abstract: A method and apparatus including a reaction chamber interposed in a polyvalent metal redox solution flow path between an absorber chamber and an oxygenation chamber, including one or more oxygenation stages, for contact in the reaction chamber of H2S-laden catalytic polyvalent metal redox solution form the absorber chamber with highly oxidized polyvalent metal redox solution from the last oxygenation stage to accomplish oxidation of the dissolved H2S species by interaction with the oxidized redox catalyst essentially in the absence of gaseous dissolved oxygen. The highly oxidized polyvalent metal redox solution, including Fe<+><3> or V<+><5>, contacts the H2S-laden solution from the absorber chamber for reoxidation of the dissolved HS<->, S<=> and any of the polyvalent metal sulfur compounds (presumably a chelated iron sulfide or a vanadium sulfide), to avoid formation of sulfate or thiosulfate salts which reduce the yield of sulfur and build up in the solution. To avoid the formation of crystals of iron sulfide or crystals of vanadium sulfide, thereby avoiding loss of polyvalent metal, the residence time of the redox solution after contact with the H2S-containing gas and prior to contacting with the oxidized metal redox soluton is limited to a relatively short time. Flow of solution from the last oxygenation stage, preferably through a valve or other circulation control device, to the reaction chamber provides controlled and continuous elemental sulfur formation in the reaction chamber. <IMAGE>
